hi! I have a table displayed using Query,but now i want to add a checkbox in each row and one placed at the header of that checkbox coloum,when i click the checkbox in the header,all those checkboxes below become selected, and then i press a 'delete'button to delete all these rows,how can I achieve this?

actually i add a selected boolean property annotated @Transient to the Entity,but i don't know how to move on.

you need some ajax attached to checkbox which parse collection and do what you want, at the end rerendering table to show changes.

Hi,

look at SEAM examples - dvdstore. There is an example of multi selecting items.
Look for searchSelections phrase in java and xhtml.

For chcecking all check boxes you need some javascript coding.
